I'm planning on doing a new gaming only build towards the end of this year, so I figure it's always good to plan things in advance. I already know what components I want to use, but I'm debating with myself about whether or not I should set up a liquid cooling system to provide high performance cooling to the dual GTX-680 SLI configuration I want to use.

I plan on using a Cooler Master Seidon 240M or a Corsair H100i to cool the CPU on the bottom mount rails, which would free up the top mounts of the case to use a 480mm radiator setup to run a cooling system for the GPUs. Any thoughts or advice on how to build a GPU cooling system and/or any components alternatives that would be better suited for what I want to build is greatly appreciated as this would be my first time making a GPU cooling system.

I'll be honest if your going to rig up the GPU's to a dedicated custom loop, toss the idea of the H100 etc out of your head and do the whole system. While the H100's and other units are not bad they don't compete with a full system, and the cost of a dedicated GPU loop + H100i comparing to adding the CPU to your GPU loop your thinking of is pretty small.

Well , to start with you need to get videocards that you can get waterblocks for .And a boot drive that is SSD will help.A motherboard that you can put waterblocks on the power section is a good thing .A pump and rez combo like the RP-1200 and fittings .
